I think they get less strict the closer to gametime since it's less likely your there just to hang out.

After kickoffs, the parking attendants and security go around to groups still in the parking lot checking for tickets and tailgating passes (at least they do in platinum).

That's why I think asking for game tickets (especially in platinum) for parking is asinine. Check the lots AFTER kickoff and be done with it. Why annoy your paying guests ($45 per space, per game in platinum) when they're just trying to get in the lot?

Oh well.
